1. Sigma Notation: The Greek letter, sigma, shown above, is very often used in mathematics to represent the sum of a series. It's a nice shorthand notation!! For example is shorthand for the series starting with the first term and ending with the ninth term of 3k. That is as follows: = 3(1) + 3(2) + 3(3) + 3(4) + 3(5) + 3(6) + 3(7) + 3(8) + 3(9)

2. Find the sum of each finite series.

5. Given the series, write in sigma notation. 1.) 6 + 11 + 16 + 21 + 26 + 31 + 36

6. 2.) 9 + 6 + 3 + 0 + -3 Given the series, write in sigma notation.
